.Application tiled February 13, 1913. Serial-No. 748,102.

To all who/m. t may concern:

lBe it known that l., Pn'rnn G. MACGREGOR, a citiaen of the United States, and resident of the city, county, and State ol New York, have invented certain new and useful .Improveniente in Automatic Fire-Extinguishers, ot which the following is a specification.

This invention relates to a device or attachment adapted to be used in connection with a tank, especially in connection with dyeing or cleaning apparatus in Which the material is cleaned in a tank containing naplitha, gasolenc or similar fluids, which are very intlammable and frequently become ignited and result in a disastrous and destructive lire which destroys the machinery and the goods contained therein.

The abject or this invention is to provide c 1 ice which may be used in con- `h these tanks and by means of Hngoishing compound is auv injected into the interior therei j occurs therein.

,K ng out the invention l provide a the tire extinguishing comt i :h is mounted upon the tank in .tuner not to interfere with its y use. llhe receptacle is provided vm i means tor automatically releasing the compound and tor distributing the same th :ifrhcut linterior oi" the tank and efitsti ely extinguishing the fire.

lin the drawings like parts in the several views have been given the same reference nu inerals.

Figure 1 is a sectionalr end elevation of a Washing or cleaninv tank showing a device mounted thereon. lig. 2 is a sectional side elevation ot' the upper *portion of Fi 1,`

taken on the line 2 2 of the same. Fig. 3 is an enlarged sectional view of a portion 'of' the device taken on the line 3 3 of Fig. 1. Fig. 4 is a top plan view of Fig. 3. Fig. 5 is a bottom plan view of Fig. 3. Fig. 6 is an enlarged detail sectional view of the lower valve support.

A Washing or cleaning tank is shown at 1 and is provided with a removable cover 2. A. revolving cylinder 8 is positioned in the tank 1 and operates in the usual manner in cleaning or Washing the material by means of the naphtha or gasolene contained there in. lt will be understood that these features ot construction form no part of the invention and are shown herein for the purpose compound to be distributed throng of illustrating the invention as applied to the machine of this ty e'.

A- receptacle 4 is Apivotally mounted at 5 upon the cover 2. projection or latch 6 from the receptacle 4 is engaged by a pair of crossed levers 7 and 8 Which hold the receptacle 4 in its inoperative position, as shown in Fig. 1, against the act-ion of a spring 9.

The crossed levers 7 and 8 are pivotally mounted at 10 on the interior of the cover 2 and are held in their closed position by means of the fusible member 11 connecting the ends thereof. The opposite ends of the levers 7 and 8 are beveled, as shown in Fig. 3,

at the point Where the same engage and.

hold the rejecting latch 6 from the receptacle 4. Should a fire occur on the interior in the tank 1, the fusible member 11 will be melted and the ressure of the latch 6 against the vbevele ends ofthese `leversvvill separate the vsame and` thus` release the receptacle 4. The spring 9 swings the receptacle 4 about its pivot 5 to 'its upright position shown in dotted outline in Fig. 1. In this position the lower end of the valve Stern 12 asses through an opening in the cover 2 and) engages a distributor plate 13 and opens the lower valve 14 and also the upper air valve or vent 15, allowingthe lire ,extinguishing compound in the receptacle 4 to be injected into the tank over the distributor plate13.

The distributer plate 13 comprises a perforated member extendin from end to end of' the tank and causes t e tire extinguishing out the interior of the same.

A temporary latch 16 may be provided for holding the receptacle 4 in its inoperative positionwhile the fusible member 11 is being 'attached to the holding leverl 7 and 8, after which it is moved out of engagement therewith leaving the device set in position to be operated in the manner described.

It Will thus be seen that a very simple attachment is provided Which Will operate automatically to inject the re extinguishing compound into a tank when a lire occurs therein.

It will be'understood that the details of construction may be changed to adapt the device for use With various forms of tanks, etc.

What l claim is: In a device of the character described, a

whereby the projecting end of said valve a stem engages said support and opens said inlet and outlet.

Signed at New York city, in the county 15 and State of New York, this 31st day of Jan., 1913.
